Input Devices and Touchscreen Calibration

Weston requires at least one input device by default. If the product has no input device, disable this requirement in weston.ini:

[core]
require-input=false

In multi-display scenarios, bind a touchscreen to a specific output through udev rules:

ATTRS{name}=="goodix-ts", ENV{WL_OUTPUT}="HDMI-A-1"

Input binding can also be adjusted through the dynamic configuration file:

echo "output:HDMI-A-1:input=*" > /tmp/.weston_drm.conf
echo "output:HDMI-A-1:input=goodix-ts" > /tmp/.weston_drm.conf

Touchscreen calibration can be configured with WESTON_TOUCH_CALIBRATION or LIBINPUT_CALIBRATION_MATRIX. Use weston-calibrator or weston-touch-calibrator to get calibration parameters.
